AUTOMOBILE-LOCK.

Original application filed. February 11, 1918, Serial No. 216,493.

nary 19, 1918.

To all whom it may concern:

Be it known that T, CiIAnLns Gr. TRosInN, a citizen of the UnitedStates, residing at Pontiac, county of @akland, Eitate of Michr gan,have invented a certain new and useful Improvement in Automobile-Locks,and declare the following to he a full, clear, and exact description ofthe same, such as will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

My invention relates to automobile locks and an object of myimprovements is to provide a lock which is readily applicable toexisting forms of automobiles at a small errpense and which shall besimple, accessible, and which shall not occupy room that is required forother purposes.

T secure this object by the device illustrated in the accompanyingdrawings in which,

Figure l is a side elevation partly in sec tion of an apparatusembodying my invention and so much of an automobile as is necessary toshow its connection therewith.

Fig. 2 is a plan View partly in section on the line 13-13 Fig. 1, thepart 01" the floor shown in Fig. 1 being omitted.

Fig. 3 is an inverted plan view oi? the parts shown in Fig. 2.

Fig. 4i is a section on the line D-D Figs. 1 and 9..

Fig. 5 is a partial section on the line E-E *ig. 2.

Fig. 6 is a horizontal section oi the portion of the casing between thelongitudinally sliding rods which carry the gear shitting forks oi thechange speed gearing showing a portion or said rods, the balls extendingin an aperture therebetween and the lower end of the locking spindle.

Figs. 7 and 8 are views similar to F ig. 6 showing the parts in adifferent position.

The present application constitutes a divi sion of my applicationpatented in the United States, No. 1,280,589.

a is the floor of the automobile, Z) is the cover or upper portion ofthe change speed gearing, and 0 0 are the gear shitting forks. f is acylindrical upward projection from the cover 2), having a ball andsocket joint 6 at its upper end. 61 is a gear shifting lever extendingthrough the ball and socket joint e to operate the sliding rods in theusual way Specification of Letters Patent.

Patented Dec. 7, 1920.

Divided and this application filed. Jan- Serial No. 212,577.

in selective change speed gearings. g g are the usual longitudinalreciprocating rods carrying the forks c. There is an aperture 8 formedthrough the cover I) transverse thereof, its axis being in the sameplane and transverse to the axes of the bearings in which the rods 9 gslide. The rods 9 g are provided on adjacent sides with notches and 9 7t72. 72. are balls inserted in the aperture 8 between the rods 9 and 9The distance of the rods apart and the size of the balls h are such thatif one of the balls is in a notch g or 9* the ball adjacent to the otherrod will permit said other rod to pass by it. Thus ii one out the rods 9or g is moved, say to the position shown in Fig. 7, the other rod willbe locked in its neutral position by a ball entering the notch g andheld therein by the displaced rod and intermediate balls, or it theother rod 9 is moved from its neutral position the rod 9 will be lookedas shown in Fig. 8. Thus either oi said rods may be moved from theneutral position but not both.

The above described construction is old and is generally embodied inautomobiles as now constructed.

To provide a lock embodying my invention 1 preferably form the cover 5with a cylindrical projection z'which passes through the floor a so thatits upper end shall be readily accessible. This projection is directlyabove the center ball 0 and the axis of its bore cuts the axis of theaperture 8 at right angles and at the center thereof. In the bore of theprojection z T fit a rotatable rod on having branches is at its lowerend forming a fork which is of such a size as to extend over the centerball h, as shown for instance in Figs. 4 and When the rod m is turned sothat its forks are at the side of the line of balls it h h as shown inFigs. 7 and 8 the balls are free to act in the usual way. l7] hen saidrod is turned at right angles to said position the forks 7c 70 areinterposed betwoen the center and end balls and thus the end balls areforced and held in both of the apertures and g. This can only occur whenthe two rods 9 and g are in the neutral position of the change speedgearing and in this position with the rod 771- turned to interpose theforks 7c 70 between the balls the two rods g are immovably locked inneutral position.

The upper end of the rod is provided With a locking arrangement whichmay be of the pin lock kind having the key a. The key hole is in theupper end of the projection j and may be provided with a removable cover00 as shown in Fig. 1 to prevent dirt getting into the key hole.

Thus to lock the automobile the driver takes the key'ains'erts it in thekey-hole at the upper end of the projection 'e' and turns the rod on tothe locking position shown in Figs. 8 and 6 when the transmission'niechanism isdisconneeted. hen it is desired to use theautomobile therod mlis againturned by-thekey a to-theposition to allowthe key actionof the r balls it.

What lelaim is:

1. In an apparatusof the kind described, two reeiprocatingrods adaptedto'=throw the mechanism in' and out of engagement,: a i plurality ofreciprocating.parts lo'cated between said rods and adapted'to engageeither one ofsaid "rodsleaving the other freeya lockingrodunconnected'with any one ofsaid: parts adapted to rotate aboutits-'axis'and extending at right angles tothe plurality of parts betweensaid reciprocating rods, said vrod being provided with an eccentric lug'integr'al withisaid rod which: is' inserted between two-o'f-said--pa1-ts by the turning of saidlockingrod-thusfiorcing said parts intolo'cking engagement with both of said reciprocating rods.

' 2. In ailapparatus: of the "kind described, two reciprocating rodsadapted to throw the mechanism in and out-ofengagement, a'plurality ofballs, located between said rods and adapted to engage either one ofsaid rods leavlng'the other free, a locking rod adapted to rotate aboutits axis and extending at docking :rod is turned the branches of thefork shall come between the balls thus locking both ofsaid-reciprocating rods.

3.111 a change speed gearing, two parallel reciprocating rods adapted tothrow the mechanism in andout of engagement, aninclosed passageextending between said rods in approximately'theaxial plane thereoit, aplurality :of reciprocating iarts located in said passage between saidrods, said rods being provided with concavities opposite and adj a'centto the ends of said passage when the rodsareintheir neutral position, alooking rodextending in aplane at right angles to said passage-andadapted to turn about itsaXis and extending into said'passage, anda-"came on the end: of: said rod: in said :pa ssage adapted" to beinterposed between said: reciprocating parts 'when the rod is turned toforce one of said partsinto each of said 0011- cavities and to bewithdrawn from between said parts'when turned about its axis toanotherposition forthe purpose described.

In testimony whereof I sign this specificati'on.
